Watershed monitoring stations map

In the map below, black dots represent 73 of the district’s water quality monitoring sites. As you place your mouse arrow over a point, the Arc Hydro-generated watershed will become visible as a red outline and the site’s project name, as well as the water body’s common name, will pop up.

Use the magnifying glass buttons to zoom in or out — zooming in will be especially helpful for viewing the smaller watersheds. In the zoomed-in mode, use the navigation arrows on the map to pan left and right, or up and down, to more centrally position your area of interest. Clicking a black dot will take you to that monitoring site’s fact page.

You can also locate the watersheds by county or by water body common name using the links on the right side of this page.
